All oftlie parts speeifieally referred: toup an d. standard equipment of. the auto vehicle are designated by letter in orderl th e inore ri eedily to distinguishvthem from the new elements which, peruse, and in con'ibihation with i the l old elements constitute the present invention.

The'pipel is introduced througl the. elbow: B .l into the tanleA withtits free end proj eoting-upxverdily and terminating at the level at which it; is desired to trap. the reserve quantity of paso line. The pipe .1 is supported, in the elbow Bbymeans of e-sleeve 4 mountedupon'the eyli-nd-1-iea1 bezurin elbow 1B.

Taberegular valve with which the sediinenti-bulb isinorinally equipped is 6 substituted therefor -said valve beingsi-niilur .to the original valve in that: it has -a port; 7 communieating rigitged by esuitable iwrenchzfor sei ewinghthe Withthe sediment bulb C and throughthe latter with the carbureter connection, but in addition it has another port 9 represented by the aggregate areas of the passages 8 shown in Figures 5, 6 and 7 into which port the passages 8 merge, said port being angularly displaced with respect to the port 7 but in the same zone so that it, too, may be put into communication with the sediment bulb and carbureter alternatively with the port 7.

The port 7 opens centrally in the rearward face of the valve 6 and is connected with the pipe 1 by means of a telescopic section 10 of said pipe which has a valve face 11 pressed into resilient contact with the valve 6 by means of a spring 12 held in compression between a flanged portion of said extension adjacent its valve face and the stationary portion of said pipe, a sleeve 13 preferably intervening, the function of which is to compress a yielding washer l l into fluid-tight relation with the telescopic joint of said pipe.

It is obvious that the threaded portion of the elbow B may be of dilierent lengths on different elbows, also that the sediment bulb fitting may be screwed farther into said elbow in one instance than in another. It may happen also that due to very slight differences in dimensions the valve 6 may seat deeper. in one fitting than into another. All of these possible circumstances necessitate the provision of a conduit of variable length between the flange 3 which bears against the sleeve 4 and the valve face 11 that engages the valve 6. The spring 12 serves not only to keep the valve face 11 pressed against the valve, but reacts also through the pipe 1, pressing the flange 3 against the sleeve l, thus holding the pipe 1 securely in place. Additional means may be provided if desired for securing said pipe, consisting of the screws 15 which engage the sleeve 4, and the heads of which overlie the flange 3.

The valve is provided with a handle J and a plate 17 having suitable indicia with which the valve handle cooperates, indicating the normal on, reserve and cut-oil? position of the valve. held against rotation by suitable means such as a slight projection 18 upset in the metal of the plate, which registers'with a corresponding groove which may be filed or otherwise formed in the adjacent face of the sediment bulb fitting The plate 17 is held in place beneath the ring nut F.

In operation the gasoline is normally supplied through the pipe 1, the outer end of which may be provided with a suitable strainer. The gasoline passes through the telescopic extension of said pipe and through the ports 7 into the sediment bulb and thence to the carbureter connection H, the normal open position of the valve being indicated in Figure 3. hen the valve is The plate 17 may be turned to the position in which the reserve supply of gasoline is discharged, the flow takes place from the bottom or the tank A into the elbow B passing through the apertures 5 of the sleeve 4; which are suiliciently numerous to assure unrestricted flow, and then through the annular passage in the sediment bulb fitting outside of the pipe 1 and its extension, thence through the apertures 8 in the .valve and through the port 9 to the sediment bulb.

In practice the construction may be somewhat simplified by omitting the sleeve 13 and washer 14, since the slight leakage which might occur through the telescopic joint of the pipe 1 will be insuiiicient to supply the fuel requirements of the engine and there fore will have no effect in preventing the stoppage of the engine through lack of fuel when the level of gasoline within the tank falls below the upper end of the pipe 1.

lVhile I have herein described what I believe to be a practical and preferred embodiment of the invention, yet it is to be understood that such changes a-nd alterations in the construction and arrangement of the several parts, as the exigencies of use may show to be necessary or desirable, may be made without transcending the scope or the invention as defined by the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent, is

1. A gasoline reserve control device for insertion in a gasoline supply tank having a longitudinally extending discharge conduit provided with a carburetor connection, said device comprising a pipe of smaller external diameter than the diameter of said conduit and adapted to be arranged longitudi nally within said conduit, said pipe having an extensible portion, a valve for insertion in said conduit and having ports for alternatively placing said pipe and said conduit into communication with said carbureter connection, and a spring normally pressing said extensible portion into valve-sealing contact with one of the ports of said valve.

2. A gasoline reserve control device for insertion in a gasoline supply tank having a longitudinally extending discharge conduit provided with a carbureter connection, said device comprising a pipe of smaller external diameter than the diameter of said conduit and adapted to be arranged longitudinally within said conduit, said pipe having a telescoping end portion, a valve for insertion in said conduit having ports for alternatively placing said pipe and said conduit into communication with said oarbureter connection, and a spring normally pressing said telescopic end portion into valve-sealing contact with one of the ports of said valve.

3. A gasoline reserve control device for conduit having ports for alternatively plac ing said pipe and said conduit into communication with said carbureter connection,

and a spring normally pressing said telescoplc end portion into valve-seallng contact with one of the ports of said valve, and

simultaneously compressing said packing means.

4. A gasoline reserve control device for insertion in a gasoline supply tank having a longitudinally extending discharge conduit provided with a carbureter connection, said device comprising a pipe of smaller external diameter than the diameter of said conduit and adapted to be arranged longitudinally within said conduit of larger diameter than said pipe, a support for said pipe engagable with the interior wall of said conduit, said support being perforated to maintain fluid communication through said pipe, the latter having an extensible portion, a valve for insertion in said conduit having ports for alternately placing said pipe and said conduit into communication with said carburetor connection, and a spring normally pressing said extensible portion into valve-sealing contact with one oi. the ports in said valve and maintaining said pipe in place relative to said support.

5. A gasoline control device for a fuel supply system including a tank, an elbow connected with the bottom of said tank and having an interiorly threaded horizontal limb, and a sedimentbulb fitting threaded partway into said elbow, said fitting having a conduit forming a continuation of the bore of thehorizontal limb of said elbow and also having a carbureter connection communicating with said conduit through said sediment bulb, a pipe of smaller diameter than the conduit of said bulb and the internal diameter of said limb, said pipe extending through the horizontal limb of said elbow and having a part thereof bent up into said tank, a support for said pipe journalled thereupon and threaded into the horizontal limb of said elbow back of said sediment bulb fitting, said pipe having a flange bearing against said support and said support being apertured to permit the flow of fluid through said elbow, a valve in said fitting having ports alternatively pla -v ing said pipe and said conduit into communication with the carbureter connection, said pipe having an extensible portion communicating with one of the ports of said valve, and a spring surrounding said extensible portion normally pressing said portion into sealing contact with said valve and simultaneously maintaining said flange in place against said support.

In testimony whereof I have hereunto set my hand.
